G090A01A-AATFILLING THE WASHER RESERVOIR
The washer fluid reservoir supplies fluid to the
windshield washer system.
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during bad weather or
whenever the washer system is in more fre-
quent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (3.0 Liters).
CAUTION:o Radiator anti-freeze (engine coolant)
should not be used in the washer system
because it will damage the car’s finish.
o The washer lever should not be pulled
and the washer should not be operated
if the washer reservoir is empty. This can
damage the washer fluid pump.
Transaxle lubricant in the manual transaxle should
be checked at those intervals specified in the

Use only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your braking
system. Follow the instructions printed on the
container.
G120D01A-AAT
To Check the Fluid LevelThe fluid level in the brake fluid reservoir should
be checked periodically. The level should be
between the "MIN" and "MAX" marks on the
side of the reservoir. If the level is at or below
the "MIN" mark, carefully add fluid to bring it up
to "MAX". Do not overfill.
G120E02A-AAT
Adding Brake FluidWARNING:
Handle brake fluid carefully. It can damage
your vision if it gets into your eyes. Use only
DOT 3 or DOT 4 specification fluid from a
sealed container. Do not allow the fluid can
or reservoir to remain open any longer than
required. This will prevent entry of dirt and
moisture which can damage the brake sys-
tem and cause improper operation.
To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour the
recommended fluid into the reservoir. Do not
overfill. Carefully replace the cap on the reser-
voir and tighten.

tion
1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:Running the air conditioning system for
extended periods of time with a low refriger-
ant level may damage the compressor.
G140C01A-AAT
LubricationTo lubricate the compressor and the seals in
the system, the air conditioning should be run
for at least 10 minutes each week. This is
particularly important during cool weather when
the air conditioning system is not otherwise in
use.
G140D01A-AATChecking the Compressor Drive Belt
When the air conditioning is being used regular-
ly, the compressor drive belt tension should be
checked at least once a month with the engine
turned off.
To check the drive belt tension, press down on
the belt halfway between the engine crankshaft
and compressor pulleys. Pressing with your
finger, you should not be able to deflect this belt
anymore than 1/3 of an inch. If you have the
instruments to check it, with a force of 22 lb.
(98N), the deflection should be 0.315 inches
(approx 8.0 mm). If the belt is too loose, have it
adjusted by your Hyundai dealer. accumulation of dirt, dead insects, leaves, etc.
These can interfere with maximum cooling effi-
ciency. When removing such accumulations,
brush or hose them away carefully to avoid

FUSES
Replacing a Fusible Link
Drive belts should be checked periodically for
proper tension and adjusted if necessary. At the
same time, belts should be examined for cracks,
wear, fraying or other evidence of deterioration
and replaced if necessary.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine. After a belt is re-
placed, the new belt should be adjusted again
after two or three weeks to eliminate slack
resulting from initial stretching after use.A fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus pre-
venting damage to the entire wiring harness.
(This could be caused by a short in the system
drawing too much current.) If this ever happens,
have a Hyundai dealer determine the cause,
repair the system and replace the fusible link.
The fusible links are located in a relay box for
easy inspection.
CAUTION:When replacing a fusible link, never use
anything but a new fusible link with the
same or lower amperage rating. Never use a
piece of wire or a higher-rated fusible link.
This could result in serious damage and
create a fire hazard.

4. Replace the blown fuse by pressing a new
fuse of the same rating into place. The fuse
should be a snug fit. If it is not, have the fuse
clip repaired or replaced by a Hyundai dealer.
If you do not have a spare fuse, you may be
able to borrow a fuse of the same or lower
rating from an accessory you can tempo-
rarily get along without (the radio or cigarette
lighter, for example). Always remember to
replace the borrowed fuse.
CAUTION:A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re-
place a fuse and it blows as soon as the
accessory is turned on, the problem is seri-
ous and should be referred to a Hyundai
dealer for diagnosis and repair. Never re-
place a fuse with anything except a fuse
with the same or a lower amperage rating. A
higher capacity fuse could cause damage
and create a fire hazard.
NOTE:
See page 6-20 for the fuse panel descrip-
tions.

Replacing Accessory Fuse
The fuse box for the lights and other electrical
accessories will be found low on the dashboard
on the driver’s side. Inside the box you will find a
list showing the circuits protected by each fuse.
If any of your car’s lights or other electrical
accessories stop working, a blown fuse could
be the reason. If the fuse has burned out, you
will see that the metal strip inside the fuse has
burned through. If you suspect a blown fuse,
follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse.
Remove each fuse by pulling it toward you
(a small "fuse puller" tool is contained in the
fuse box to simplify this operation).
3. Be sure to check all other fuses even if you
find one that appears to have burned out.
